The Mariah Owners Club - Any known problems for 2001 Z250 SHABAH?

Yesterday i purchased a 2001 Z 250 SHABAH with the 454 motor. This is by far the biggest boat I have ever owned. I purchased from a dealer that took it in on trade. Its a one owner boat with only 349 hours. They were asking $15,000 and I was able to purchase for $12,900. I'm curious to know if anyone has anything negative to say about this model and also would like to know of any positives about the boat in general. Any suggestions on a good GPS and depth finder that I should purchase that isnt very expensive and also if anyone has a picture of this model boat with a wake tower on it or a swim platform because I will be adding both to mine. I have found the wake tower I want to purchase but have yet been able to find a swim platform or even an idea of what it will cost to buy one and have it installed? Any info you could give me would be great. Thank you so much
